Cisco Exam 300-620 Topic 9 Question 71 Discussion

Actual exam question for Cisco's 300-620 exam

Question #: 71
Topic #: 9

Refer to the exhibit.

Refer to the exhibit. Server A is connected to the Cisco ACI fabric using two teamed interfaces. One interface in a team is configured as active and the other remains in standby mode. When a failover occurs and the standby interface becomes active, it uses its built-in MAC address to send traffic. Which bridge domain configuration must be applied to resolve the issue?

AConfigure Hardware proxy.

BSet L2 Unknown Unicast to Flood.

CEnable ARP flooding.

DActivate Limit IP Learning to Subnet.

Hmm, that makes sense. It could prevent communication issues during failover.

I believe enabling ARP flooding might also be a valid solution.

That's a good point, Enabling ARP flooding could potentially help as well in resolving the issue.

I agree with you, Setting L2 Unknown Unicast to Flood will allow the standby interface to send traffic with its built-in MAC address during failover.

I think the correct answer is B) Set L2 Unknown Unicast to Flood.

Yeah, that makes sense to me. If the standby interface takes over, its MAC address will be different, so flooding the unknown unicast traffic seems like a reasonable solution.

B) Set L2 Unknown Unicast to Flood - that could also work, as it would ensure that the traffic is flooded to all the ports in the bridge domain, rather than relying on the MAC address.

For sure, it's a simple but effective way to handle failovers in the network.

Hmm, I'm leaning towards option B - 'Set L2 Unknown Unicast to Flood'. That sounds like it could help deal with the MAC address change by flooding the traffic instead of trying to learn new MAC addresses.

Hmm, let's look at the answer options. A) Configure Hardware proxy - that could be a good option, as it might help maintain the virtual MAC address even when the standby interface becomes active.

I think the key is figuring out how the bridge domain configuration can resolve the MAC address change problem. We'll need to look closely at the options provided.

Exactly! If the MAC address changes, it could lead to connectivity issues and disruptions in the network. We need to find a configuration that can resolve this problem.

Haha, the 'Limit IP Learning to Subnet' option sounds like it's trying to limit the problem rather than solve it. Let's not go for that one!

Alright, let's think this through. From the information provided, it seems that when the standby interface becomes active, it uses its own MAC address to send traffic. This could cause some issues, right?

This question seems to be testing our understanding of Cisco ACI and its bridge domain configurations. I'm not sure I'm completely confident in my knowledge of this topic, but I'll do my best to contribute to the discussion.
